Application filed February of the vert-ical swinging boom which supports the pan from which the adjustment o the pan and chute may he controlled, and to support said operators house in such manner that the floor of the house will remain horizontal in all positions of adjustment of thev boom. v

Reference should be had to the accompanying drawingsl forming a part of this specification in which' Fig. 1 1s a side elevation showing the front portion of the car elevator and dumper, the pan boom, the telescopic chute and the operators house at the outer end of the boom, an adjusted position of the boom, chute and operators house being shown in dot-ted lines; Fig. 2 is a side elevation showing the boom chute and operators house in the position in which they are held when not in use, i. e. swung to their uppermost position to leave the space in front of the dumper clear for the passage of vessels; Fig. 3 is a front elevation of the dumper; and Fig. 4 is a plan view of the interior of the -operators house.

rlfhe accompanying drawing shows the front portion of an elevator structure 1, in which is mounted a vertically movable car carrying cradle 2 which is adapted to be lifted to the desired height and tilted to discharge the contents of the car held thereon. 40 Upon the front of the elevator struct-ure 1 there is mounted a vertically swinging boom 3, which supports the material receiving pan, which at the inner end of the boom has a width somewhat greater than the length of a car, so that the pan is adapted to receive all the material discharged from the car when the car carrying cradle is tilted to dump the car.

yllhe boom 3 is pivotally supported on vertically sliding heads 5, one on each side of the cradle elevator, and these heads are adapted to be adjusted up and down by means of vertical adjusting screws 6, which are simultaneously operated by means of a shaft if@ 6a, geared to the two screws and driven by e, was. seran no. 87,150.

I asuitab'le electric motor (not shown). The

boom 3 may be swung vertically about its pivots by means of hoist cables 7 which pass over sheaves 8, supported on the boom adjacent the outer end thereof. The material receiving pan 4, tapers toward its outer end and discharges into aI telescopic chute 9 which is flexibly suspended from the outer end of the boom. rl`he chute 9 is made up of a number of telescopic tubular sections which may be collapsed or expanded by means of cables 10 which are connected to the lowermost section, pass over sheaves 11 and 12 at the outer end of the boom, and about windinr drums 13 which are operated by an electric motor 14 supported on a platform carried by the boom above the pan. rlhe chute 9 may also be swung laterally by means of cables 16 anchored to the boom outwardly beyond the chute 9, and passingover sheaves 17, 18, 19, 20 and 21 to winding drum 22., driven by a motor 23 also mounted upon the platform 15.

At the lower end of the chute 9 there is a trimmer 24, which ma be operatedby a motor 25, mounted on t e lowermost section of the chute. The structure so far described is all old and well known, the pan, telescopic chute and trimmer being ordinarily employed for transferring material from railway cars to the hold of a ship.

The present invention consists in the provision of an operators house supported from the boom upon the outer side of the delivery chute, in such manner that an operator in the house can conveniently control all the movements and adjustments of the boom, chute and trimmer. For supporting the opeiators house two spaced frames are provided, each consisting of a rigid bar 26, secured to the.

boom adjacent the outer end thereof above -the pan, and projecting outwardly beyond the chute 9 and a brace bar 27 secured adja- 'cent the outer end of the bar 26 and to the outer end of the boom adjacent the bottom thereof.

rEhe two frames formed by bars 26 and 27 are secured to opposite sides of the boom and extend parallel with each other, the outer ends of the bars 26 being connected by a cross-shaft 28, from which is pivotally suspended the operators house 29. The width of the operators house is less than the space between the supporting bars 26, so that the operators house is free to swing to a position in which the floor of the house is horizontal,

regardless of the position to which the boom maybe adjusted. At the inner end thereof the operators house is provided with a projectiug platform 30, which when the boomis inoperative position is positioned beneath the lower end of a stairway 3l, mounted on the boom andoverhanging the outerend thereof. The stairway 31 leads to a stairway 32 along one side edge of the material receiving pan 4, and the inner end oi this stairway is adjacent a ladder or stairway on the elevator structure l, the stairway 33 leading tothe main operators house 34- on the structure l, from which the cradle elevating and dumpinginechanisni is controlled.

The electric motors driving the screws for adjusting the pan boom vertically, for operating the boom swinging cables, for operating the chute telescoping and swinging cables and for operating the trimmer are yallconvtrolled by the operator in the house 29, suitable controllers 35, 36, 37, 38 and 39 being mounted at convenient points within the operators house, so that the operator within the house can operate any of these motors at will, to provide the desired adjustment.

Having described my invention, I claim: l. In combination with a car dumper, a

vertically swinging boom having a pan adapt- 30 ed to receive material from cars on the dumper, mechanism vtor swinging the pan, an operators house from which said mechanism is-controlled, and means carried by the boom and extending upwardly with respect to the pan for pivotally suspending the house clear of the pan in all positions ofthe boom.

2. In combination with a car dumper, a vertically swinging boom having a pan adapted to receive material from cars on the dumper, mechanism for swinging the pan, an operators house from which said mechanism is controlled, and means carried by the boom adjacent the outer end thereof and extending upwardly and outwardly with respect to the outer end of the pan for pivotally suspending the house clear of the pan in all positions ot' the boom.l

3. In a device of the character described, a vertically swinging boom, mechanism for swinging the boom, an operators house from which the mechanism is controlled, and means carried by the boom and projecting beyond the outer end thereof for pivotally suspending said house in a position to clear the end of the boom as the same is swung vertically.

a car damper, a

a. In combination with vertically swinging boom having an outwardly tapermg pan adapted to receive the material dumped from a car, a chute depending from the outer end of the boom and adapted to receive the material from said pan, said boom having an extension projecting beyond the chute, and an operators house pivotally mounted on said extension to swing clear of the pan and chute.

5. In combination with a car dumper, a vertically swinging boom having an outwardly tapering pan adapted to receive the material dumped from a car, a telescopic laterally swinging chute depending from the boom and adapted to receive the material from the pan, means for swinging the boom, means for telescoping the chute, means for swinging the chute, a support rigidly attached to the outer end of the boom and projecting outwardly beyond said chute, an operators house pivotallv mounted on said support to swing clear o the pan and chute, and controllers in said house for controlling the operation 'of the boom swinging, chute telescop ing and chute swinging means.

6. In combination with an elevator structure having means for elevating and dumping a car, a vertically swinging boom having an outwardly tapering pan adapted to receive the material dumped from a car and mounted for vertical movement bodily along the front of said structure, a telescopic chute pivotally suspended from the outer end of the boom, a trimmer at the bottom of .said chute, a rigid support carried by the boom and projecting beyond the upper end of the chute, an operators house pivotally mounted on the support to swing clear of the pan and chute, and means in the operatorshouse for controlling the swinging and vertical adjustment of the boom, the telescoping and swinging of the chute, and the operation ot' the trimmer.

7. In a car dumpcr, an elevator tower struc ture having means for elevating and dumping a car, a discharge pan pivoted adjacent one end to the tower structure so as to swing vertically therefrom, a chute pivotally connected to the free end of the discharge pan, and an operators house pivotally supported by the .discharge pan adjacent its free end and independently of the pivotal connection between the pan and chute.
